Rolling Moment Characteristics of a Planing Hull with Wedges.

Active / Technical Report | Accession Number: ADA022555 |

Abstract:

Captive model experiments were conducted to determine the roll moment producing capability of wedges appended to high speed planing hulls. The experiments determined the effects of wedge angle and wedge longitudinal position on the rolling moment produced for a range of speeds. Bare hull experiments were conducted at various roll angles to determine the magnitude of righting moment desired for the specific model hull used in the experiments.
